My invention is fully shown in the accompanying drawings, in which:

reinforcing bars, or, in some instances, carryin I the same with them.

n the use of reinforcing structures of this character, there are a number of difficulties, among which may be mentioned the excessire freight incident to the shi ping of heavy structures, the bulk of the rigi 1y built structure, and in the case of the reinforcements erected on the jbb, the time that must be consumed in fittin and securing the elements of the same toget er. All of these objections are ohviated b% the usehf the folding structure foriningt e subject of my invention? In Fig. 1, 1 represents a series of stirrups "5i suhstnntiull the same size shape and we" ht of meta which are distrihuted in any i the beam. in order to resent the greatest support when in use. omb' edwiththese stirrups is a. series of light rods 9, in the present instance four innumber, set at points which will represent suhstantiallyjthefour corners of beam or girder. j These bars are stumps by meahsof wire ties .such as areillustreted in'-"Figs..-8, 9 1Q en ll, nndhareof such it n t m edrsl gph d that w on the stri'ieture' is finished i ongitudmul eas geneti -ups fern 1 hinges andlpermit ili gsuchect on. Such co epslng or bending on the hinges will not affect the frictional en egement of the several parts, and-hence t, f IejS no danger of any of the stirrups chung'n.g flieir position or working loose ,with respect ,tti thelongi tndinal rods when such "reinforcement is may be carried out in the erection of posts,

' columns or similar structures where the longitudinal reinforcing bars posed, such, for instance, as'is shown in F 1g. 4, which. illustrates rectangular spac ng members 4 to which vertical rods 5cm tied by. the members 3; the tying members being of the -form illustrated in R ga. 8 and 11.

' Referring to'the enlarged views, Fig. 12,

- stirrups wit brought jection lying at right anglesto said colla si the longitudinal posed be ifi w of tie ml bars or rods 2 and the upper portions of the stirzups 1 such tie bein shown-in the normal shape efore use in 1g. 8. It consists of a wire member having two substantially 'arallel runs 10 and 101; the run 10 being n r than 10. The runs 10 and 10 are joineg by a loop 11 and said runshave hook ortions 12 and 12, respectively. The loop f this tie is, caught under one of the bars or rode; the runs 10 and 10 are then down over the bar or stirru probar or rod, and then the hooks 12 and 12 in the order named are caught underneath the bar or rod in the manner clearly shown in- 'Fig. 12. This arra ement permits either memrespect to the other, and when the members areassembledin proper relation to each other, such for instance as in the manner illustrated s. 1 and 4, the structure me be readily co apsed as is illustrated in F s. 2 and 5. It' will be noted, however, t at in order to ermit this -ro s are disv the lower cross-runs of the stirrups, the tie members forming with the bar or rod a p which'the projection of the stirrup may turn. V

For use in connecting the lowercross-runs of the stirrup' with the longitudinalbars or rods, I may use a tie member of theft? shownin normal shapein 1'9 and in th: ggsition of use in Fig. 18 r comprises a structurehavingla'loop portion 13 toIengagethe rod, from-.whi h a run 14 ex tendg termiiia gage the crossErun of run 14} extends from andlpa'sses over said In a foot; endbfaid run he: W031i a hook 15 which is caug lfl e-stii'rup. -Aiiother said loop portion--13 provided over the The foot or support wh ch this form .PXOYIGQS raises the stirrup above the centeringas illustrated in Fig. 8, and at-thc same time obviates the necessity of using their upper ends in enga ment with t e c'enterin fl in order to raise them to. the'proper heig quired layer. o f concrete beneath the beam or g1 der-;-

In Figglfl, I have shown a orm of tie with two supports or feet. is may be used when the weight of the reinforc' is exceptionally great. This permits e use of strai ht arm rejections for the stirrups. If the agona y isposed arms are used, such as'shown in Fig. 6, ties of'the form shown n 8 and 11, may be em loyed. 11 I gave shofvisih-anothe?I igrmmgf rm i norma apean 14: in-thc pos1t1on of use.

In the manner of atthe ing it to reinforcing rods which cross each other; as shown in the, drawin s, the hook 17 may engage the horizonta rods, while the hook 17 mayengage the vertical rods. Such arrangement,.of course, depends upon which of the rods the loop 18 of the member is applied, for while it will act equally well when disposed in a position substantially at right angles to the structure shown in Fig. 14, it will be on, the o posite side of the crossing portions of t e rods. Y

Itis obvious, of course,- that other forms of ties capable of performing the function desired in structures of this character may be employed with equal facility, and my-invention'is not limited to'the usedvf any specific form of tie or those shown'hercin.
